[counterintuitive] system prompts are secure and hidden from users

Never put secrets \(API keys, passwords\) or critical security logic solely in the system prompt. Treat system prompts as user-visible UI and use external guardrails for security.

Journey Context:
Developers treat the system prompt like server-side code, assuming the LLM acts as a secure sandbox. In reality, prompt injection, jailbreaks, or simple 'repeat your instructions' tricks easily extract system prompts. The LLM is a text-completion engine, not a trusted execution environment. Security must be enforced outside the model via permissions and guardrails.
